MANUFACTURE OF RADIATORS.

To all whom it may concern:

Be it known that we, HERMAN Rnis and ERHARDT BEHRINGER, citizens of the United States, and residents of the borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in the Manufacture of Radiators, of which the following is a specification.

This invention relates to the manufacture of honey-comb radiators, made of an assemblage of small tubular elements.

The object of the invention is to enable radiators of this character to be produced by a far quicker and cheaper method than heretofore.

I-Ieretofore such tubular elements have been provided with hooks at one end only, so that the tubes had to be assembled in a definite manner, with the hooked and plain ends of the elements alternating at both sides of the assemblage. Tubes have also been provided at both ends with return bends or lips, which are differentiated beforehand at different sides, by different heights and different widths of throat, into spacing members and uniting members, so that each tube had to be specially positioned with relation to its neighbors; certain of the uniting lips being further differentiated so as to engage each two other tubes to produce a staggered assemblage. In these and other cases employing pre-hooked tubes, the time and expense of associating the elements after a certain definite scheme or order constituted a considerable factor. In another mode of construction, hooks are bent over, after the tubes have been associated in position, so as to unite the tubes together; but this method is comparatively slow, and has, furthermore, no relation to this invention which has to do with the making of radiators from pre-hooked elements.

In accordance with the present invention the radiator is made of pre-hooked tubes, which have similarly hooked lips at both ends and all sides, so that the lips may act indiscriminately as spacing or clasping members, according as they happen to find themselves over or under their neighbors. As many of these tubes as are necessary to make a radiator are associated indiscriminately side by side, so that the lips come indiscriminately over and under each other; then these associated tubes are forced into Specification of Letters Patent.

end alinement and lip-engagement sufficiently firm to insure that the honey-comb structure will maintain its interconnected assemblage (integrity) until soldering at the ends of the tubes, which constitutes the last step in the process.

In the accompanying drawing illustrating the invention: Figure 1 is a view looking at the ends of a few associated elements showing how the lips take over or under each other; Fig. 2 is a fragmentary plan view of the support or table preferably used in assembling the tubes, a few of the guiding and positioning pins being shown; Fig. 3 is a side sectional view showing tubes, one in elevation and the others in section, on the pins, and indicating means for alining the elements; Fig. l is a side sectional view of a modified form of apparatus; Fig. 5 is a fragmentary perspective view of a few elements assembled side by side before soldering; Fig. 6 is a fragmentary sectional elevation of the end portions of a few assembled tubes after soldering; and Fig. 7 is a perspective view of one of the pre-hooked tubular elements from which the radiator is made.

o first make or provide ourselves with tubular elements 10 such as shown in Fig. 7. These are preferably square, and are of uniform width throughout including the end portions. The sides are provided each with a longitudinal groove or corrugation 11, stopping short of the ends, to strengthen the tubes and afford water reservoirs. The tubes are all provided at both ends and all four sides with similarly hooked lips 12. These elements are indiscriminately associated side by side. By indiscriminately we mean that it makes no difference which ends or sides of the tubes come together or which go over and which under. They are merely associated side by side to form straight rows in both directions. The elements are preferably associated by being internally guided to and held in position side by side in predetermined proximity to each other. This is accomplished in a very simple manner by placing them over pins 13 projecting upwardly from a table or support 1 1-. By means of these pins the tubes are reliably brought and held in proper re lation. As shown, the upper and major parts 15 of the pins are cylindrical and materially smaller than the interior of the tubes and their lower parts 16 are flaring,

(lit

so as to afiord V-shaped recesses in which the lower lifted ends of the tubes are received and by which they are brought close together. In the simplest procedure the operator takes the pre-hooked tubes in groups or handfuls, holds them over the position devices or pins, and jiggles or shakes them so that they drop over the latter. hen the support is filled, the loose collection is formed and fixed, that is, the tubes are forced into end alinement and the lips into firm or close engagement. This may be accomplished by merely exerting downward pressure on their upper ends by a plane leveling device, indicated at 17. This action squeezes together the lips at the lower end of the tubes, which are forced farther into the Vs. Of course this operation may be performed from time to time, upon partial areas, during the association of the tubes. It will be obvious that the upper ends of the pins may be caused to act as stops to limit the downward movement of the pressure device.

. Fig. 4- illustrates means by which the lips ma be squeezed at both sides of the collection, that is to say, at both ends of the tubes. In this case the pressure member 1'7 has socketed, tapered bosses 18, which take over the upper ends of the pins and act upon the lips in the same manner as the inclined sides of the pin parts 16. This View shows also how the collection of tubes may be stripped from the support, as by means of a stripper plate 19-.

The formed and fixed collection, which is I sufliciently rigid to stand handling, is now soldered at both sides, that is, at both end portions of the tubes. Fig. 6 indicates the approximate depth to which it is desirable to cause the solder to extend. This permanently unites the tubes and closes the ends of the spaces left between the tubes for the circulation of water. The soldering may be conveniently effected by dipping first one side and then the other of the collection into a solder bath.

Having described our invention, what we desire to secure by Letters Patent and claim is 1. The method of assembling honeycomb radiators, comprising indiscriminately associating and impaling side by side in predetermined proximity a plurality of tubular elements having similarly-hooked lips at both ends and all sides, with their lips indiscriminately over and under each other, then forcing the elements into end alinement and firm engagement.

2. The method of assembling honey-comb radiators, comprising placing a plurality of tubular elements having similarly-hooked lips at both ends and all sides over internal supports in an indiscriminate manner, then forcing the elements into end alinement and simultaneously forcing the lips into firm engagement and finally soldering the collection at the end portions of the elements.
